SPECIFICATION forming part of Letters Patent No. 287,229, dated OctoberApplication filed June 14, 1883.

T all whom t may concern:

Be it known that I, JAMEs H. BULLARD, of Springfield, in the cunty ofHampden and State of Massachusetts, have invented a new and usefulImprovement in Fire -Arms, of which the following is a description andspecification. Y

My invention is an improvement upon the device shown in thepatent to B.F. Henry, of October 16, 1860; and its object is to remove much of thefriction in the operation of cocking the hammer, in moving theoperatinglever forward,' and thereby moving back the breech-pin andpiston, and to render the movement ofthe operating-lever more uniform asto the power required to operate it and the mechanism connectedtherewith; and I accomplish this by the mechanism substantially ashereinafter described, and illustrated in the accompanying drawings, inwhich- Figure I is a longitlulinal vertical section of so much of thearm as `is .required to show my invention as applied thereto at line A.Fig. II is a horizontal section of the same at line B, both theseillustrations showing the operating mechanism in position with thehammer thrown forward. Fig. III is a longitudinal section with theoperating mechanism in position, with the hammer thrown back or inposition of full-cock; and Fig. IY is a modiiication of the invention.

In the drawings, 2 represents the frame of the arm; 3, theoperating-lever; 4, the carrierblock; 6, the arm operating the carrier;5, the hollow breech-pin; 7, the piston with the firing-pin forward; 10,the. link, pivotd at its forward end to the breech-pin; 12, the brace,pivoted at its forward end to the rear end of the link, and at its rearend to the frame, and which is also provided with a slot which engageswith a pin, 16, in the upper end of the operating-lever 3, this link,slotted brace, and pin in the upper end of the operatinglever,

combined, operating to move back the hollow breech-pin and piston, and,as heretofore constructed, lto cock the hammer by forcing back thepiston against its nose. All these parts before mentioned, asordinarilyconstructed, are well known, and are shown in the patent to B. F. Henry,before mentioned; in that to O. F. \Viuehester, of September 4,

1866, and others, and require no further description, as theaccompanying` illustration.

with the exception of my invention applied thereto, as hereinafterdescribed, shows the operating mechanism of the arm as ordinarily andheretofore constructed.

It will be evident upon inspection that as the link 10 and brace l2 aredrawn downward by the upper end of the operating-lever 3, and as theupper end of the latter moves down into the position shown in Fig. III,a very great increase of force or power is required to be exertedagainst the operating-lever to bring the hammer into the position shownin Fig. III. the parts shown in Fig. III, in which the upper end oftheoperating-lever 3 is in a position, during the latter portion of themovement ofthe parts in cooking the hammer by moving forward the lowerend of the operatinglever and drawing down the link 10 and brace 12, toforce the piston backward againsthe nose ofthe hammer. In this positionit will be seen that the upper end of the operating lever extendssubstantially at right angles to the length of the link IO-ihc mediumthrough which the breech-pin is drawn back by the upper end ofthepperating-lever, und consequent] y the medium through which the pis ton7 is forced back against the nose of the hammer to cock it, asordinarily constructed. Ot' course, under that construction, the poweris applied to the operating-lever to cock the hammer under the greatestdisadvantage, and

'more especially is this the case when it is considered that as thelower part or" the lever is being moved forward and the hammer commencesits backward movement, the mainspring becomes more and more rigid andstiff as the backward movement of the hammer straightens it.

rlhis will be obvious upon examination of 'Ihc consequence is that theoperating-lever moves forward with a very- IOO the force required tomove the hammer backward, seems to have very little effect upon theforward movement ofthe lever.

'In the upper end of the operating-lever 3, I

5 'pivot at 15 an arm, 14, which curves around the pin 16, which engagesin the slot of the brace 12, to operate the latter with the link l0,

and the rear end of this arm 14, I pivot to a link, 18, which is pivotedto the hammer in the recess 17, inthe front side thereof. f rIhis Alink18, however, is not essential to the successful operation of theinvention, and is only for the purpose of holding up the rear end of thearm 14 in certain positions of the operating-lever 3, as when the hammeris at full-cock l and .if the hammer were let forward therear end of thearm 14 would strikethe front side of the hammer and would slide up alongthe front. side Yof the hammer as the latter was moved forward until itreached and abutted against the top of the reccss17l in the hammer.

When constructed in this manner, asl shown in 'Fig'. IV, and without thelink, if the parts should be operatedv very fast, this falling of therear end of the arm 14 and striking against the. front side of thehammer vand sliding up against the shoulder 17, as shown in Fig. IV,into position to again force back the hammer fto the position offull-cock, would be accompanied with more or less noise, and I prefer topivot the rear end of the arm 14 to the link 18, which serves thepurpose of aguide to hold up the rear end of said arm and guide itdirectly to its position against the hammer without first striking thelatter lower down and slidingup to position, and preventing the noiseresulting from the action of those' parts. As the mainspring is weakestwhen the'hammer is thrown forward, a certain amount of power is'required to be exerted against the lever 3 in moving it forward, and asthe hammer continues to move back the mainspring becomes more and morerigid and stiff; but as the upper end of the operating-lever continuesto move back, the pivot 15', which secures the arm 14 to the `upper endof the operating-lever, is brought nearer andrlnearer into line with thepivot'upon which the operating-lever nieves,

and the point of. pressure ofv the rear end of the arm 14 against thehammer until the latter is brought back intoa position of fullcock,where the position of thelever 3 and arm 14 andhamnier is shown inFig.III. In-

. asmuch as the power is applied directly from l be the lever 3to andagainst the hammer, through the medium of the arm 14, in the operationfof cocking the hammer, no pressure ofY the piston against the nose ofthe hammer is re- `quired or can occur, because with my inventionapplied the hammer commences its backward movement in advance of thebackward movement of the piston 7, and owing-to the direct backwardmovement ofsthe arm 14 the hammer moves backward, even after it starts,much faster than thc piston moves, and arrives at its position offull-cock slightly in advance ofthe piston, the rear end of the latterbeing cut away at 8 on the under side, so that it may not strike againstthe nose of the hammer as the piston arrives at its backward position.In this construction the nose of the hammer and the rear end of thepiston are not worn or injured, as no contact of the two occurs exceptwhen the arm is discharged.

Having thus described my invention, what I claim as new is 1. 'Ihecombination, with the frame of a firearnr, ofthe sliding breechpin 5,containing the firing-pin, the operating-lever 3, pivoted in said frame,the'brace 12, pivoted at its rear end to the frame and toggled to theupper end of said operating-lever, the link 10, pivoted at its rear endtothe forward part of. said brace, and at its forward end to saidIsliding breechpin, the hammer 9, and the arm 14, pivoted at its forwardend to the upper end of said operating-lever, and with its' rear partbearing against the hammer, whereby the sliding breech-pin andfiring-pin ,are moved back by said brace and link, and the hammer iscocked by said arm when the operating-lever is moved forward,substantially as described.

2. The combination, with the frame of a {irc- `arm, of the slidingbreech-pin 5, the operating lever 3, pivoted in said frame, the brace12, pivoted at its rear end to the frame, and toggled to the upper endof said operating-lever, the link 10, pivoted at its rear end to theforward part of said brace, and at its forward .end to said slidingbreeclrpin, the hammer 9,

and the arm 14, pivoted at itsA forward end to the upper part of said.operating-lever, and with its rear end bearing against the hammer,whereby the sliding brecch-pin and firing-pin are moved back by saidbrace and link, and the hammer is cocked by said arm when theoperating-lever is moved forward, and a guidepiece, 18, pivoted at oneend to said hammer and connected at its other end with said arm, toguide the rear end of said arm always into the same position andpreventnoisein the working ofthe parts, substantially as described.
